Summary: The standard that introduced efficiency of domestic active inhaler detects method -- air dust counting method, pointed out this efficiency detects actor defect of the method. The standard that introduced the national inhaler efficiency such as current Europe, beauty in detail detects counting method of diameter of bead of methodological stretch collosol, mix with gas collosol, testing instrument from the experiment the efficiency that efficiency label just faces Europe, beauty 3 times detects the method undertook detailed analysis is compared. Listed counting method of diameter of gas collosol bead relatively the advantage of air dust counting method, put forward to use counting method of diameter of gas collosol bead to detect then the viewpoint of inhaler efficiency. Defined counting method of diameter of bead of the collosol that use gas detects the operation method of inhaler efficiency.

Our country in 20 centuries 60 time had begun to be engaged in air the research of clean technology, can make an inhaler. As modern industry and communal and safe consciousness rise, the application of clean technology is wider and wider, the check mark of the purifying device such as filter also is growing ceaselessly definitely. But at present home detects the system is not perfect still, of the inhaler in GB detect counting method of one air dust did not get the means edit, put in certain blemish, cannot satisfy the need that at present filter industry production admits. Accordingly, in inhaler standard edit in the job, search more reliable, more reasonable inhaler to detect the method is a very main job.
Counting method of 1 air dust
1. The principle of counting method of 1 air dust
20 centuries at the beginning of 80 time, worker of domestic scientific research put forward to use counting method of atmosphere grit diameter to regard as general and ventilated detect with the inhaler methodological thought, include a country the level namely GB12218. 89 " general and ventilated with method of inhaler function experiment " . Undertook editing to this standard 1993 and continue to use up to now.
Detect with air dust counting method the efficiency of the inhaler, place is air dust with dirt source. Home is active detect the standard of the inhaler (GB12218. 89) made specific provision with air dust to the experiment: Outdoor or the indoor air that is the same as with the photograph outdoor; ≥ of diameter of the bead in atmosphere 0. 20000 / rise the computation chroma ≥ of 5 LLm particle; ≤ of air relative humidity 75 % , 5 ℃ of temperature ≥ " .
